Just downloaded your project and trying to build/run it but not having luck.
I’m using Nexus 7 running latest version of android.
appears that the apks in the “Recent Builds” don’t run — so I ran the source code in android studio and got the following error:

Ok sorry for being a noob, how exactly do you build it. I have forked your repo, and opened the project in Android Studio 4.2 and it is asking for config? it says it is only for Android Studio 1.5.1 is that correct? That's a five year old version of android. Yikes!

3:22 PM	Gradle sync failed: Unsupported method: SyncIssue.getMultiLineMessage().
				The version of Gradle you connect to does not support that method.
				To resolve the problem you can change/upgrade the target version of Gradle you connect to.
				Alternatively, you can ignore this exception and read other information from the model.
				Consult IDE log for more details (Help | Show Log) (10 s 255 ms)

I´m getting a lot of warnings "The project 'CarBusInterface' is not a Gradle-based project"

This is less of an issue and more of a question as to whether this has the functionality. I am interested in disabling a "video in motion" feature. Essentially, the car can allow for a rear auxillary input in which you can display video, ie gauges, on the stock headunit. However, the stock functionality blocks this ability to have the video play while the vehicle is in motion.

My question is, can CarBusInterface listen to the BUS traffic and if it sees the command, block the given command, or immediately issue another command to disable it.

Given of course I know what the commands are. If the listening portion is possible, then it will be possible to find the command.

Question answered via email.

Hi there,

I was doing some data analysis and compared your application to some other apps and found that people are really loving tutorials on various setups like setting up their obd2 and it would be a great asset for your app if you include it too.

Does anyone work on it? Is there any chance co connect via Wifi?

It's not an issue but it would be cool to have an option to use bluetooth or usb-serial. I saw your Steering-Wheel-Interface project, but it looks like you will not support it any more.

The android:versionCode is an integer that get's checked when an app checks for updates. Your verion "name" gets bumped, but for Android this is just renaming an already delpoyed verison, namely versionCode 1. Update this integer with every release.

Hi,

I did some analysis on your applications and some other applications and found that people highly praise good scanners in such applications so as to easily connect their vehicles without going through a long procedure of typing all the details. It would be really good to have something like that in the applciation.

It would be nice to have release apk's on GH release tags info.

Hey there,

i would love to see a feature to use conditions like

• is the car radio turned on?
• is MP3 (Aux) the selected source?
• is the radio muted or not?

I want to use the steering wheel to controll the media on my tablet in the car but only if the radio is set to mp3. The codes/ids to read that from canbus can be found on the internet (for example audiforum.us or janssuuh.nl)

i upgraded my Sony Xperia Z2 tablet (Verizon model SGP561) from Kitkat 4.4.x to Lollipop 5.0.2 and now the app rarely works without first manually issuing a command in the debug terminal. there are no errors or crashes, and no errors were noticed in logcat either. the app appears to connect OK, but never begins receiving bus data from the ELM adapter without the manual command.

some part of the service looks like it may be "hanging" during launch. sending any command form the debug terminal causes the startup commands to be issued again and everything begins to work. note that just using the menu option "re-send startup commands" in the terminal does not work though.

i've tried manually launching the app as well as using the "automatic launch" setting, neither makes a difference.

i am using version 1.0 of the app (car_bus_interface_v1.0-debug.apk)

Awesome app! It's great having Tasker monitor support, but is it possible to have support to send commands from Tasker as well?
I tried using an app called SerialBluetoothTasker, but something about it isn't working. I can see lights flash on the adapter when it sends the command, but I think maybe it cuts off the stream before the whole command is sent or something strange like that. I actually tried to write my own Java functions in Tasker as well but had the same results. Your app has been the only one that I can get to reliably send commands.

It would be really nice if there were step by step build docs for new users. Currently it's guess work.

Hi, i use your app (build on android studio, not your direct apks) with Android 9 xiaomi mi 8.

i use also a ELM327 OBD2 Bluethoot on my Opel Astra K.

In your app, on debug terminal view i view nothing cuan bus records.

i have this error on logcat:

2020-02-13 13:40:25.718 31156-2079/com.theksmith.android.car_bus_interface W/CBIServiceMain: BTConnectThread.run() : failed to connect : exception= read failed, socket might closed or timeout, read ret: -1

at com.theksmith.android.car_bus_interface.CBIServiceMain$BTConnectThread.run(CBIServiceMain.java:532)

what is the problem?
can i have a tutorial that explain how can use your app to debug every obd2 and canbus data?

regards,
